Excerpts from Books and Wikipedia
"The First Atlantic system was the trade of enslaved Africans to, primarily, South American colonies of the Portuguese and Spanish empires; it accounted for slightly more than 3% of all Atlantic slave trade. It started (on a significant scale) in about 1502." The Atlantic slave trade was abolished by Britain in 1807. The last recorded slave ship to land in the U.S. was in 1859. Slavery was abolished in the U.S. in 1865. "In Brazil, however, slavery itself was not ended until 1888 making it the last country in the Americas to end involuntary servitude." About 10 million slaves arrived in the Americas between 1519 and 1867 with the following distribution: Portuguese America (38.5%), British America minus North America (18.4%), Spanish Empire (17.5%), French Americas (13.6%), British North America (6.45%), English Americas (3.25%), Dutch West Indies (2.0%), and Danish West Indies (0.3%).
